METHOD FOR PARAMETRIC SPATIAL AUDIO CODING AND DECODING, PARAMETRIC SPATIAL AUDIO CODER AND PARAMETRIC SPATIAL AUDIO DECODER |
摘要 |
<p>A method for parametric spatial audio coding of a multi-channel audio signal comprising a plurality of audio channel signals is provided, the method comprising: calculating at least two different spatial coding parameters for an audio channel signal of the plurality of audio channel signals, selecting at least one spatial coding parameter of the at least two different spatial coding parameters associated with the audio channel signal on the basis of the values of the calculated spatial coding parameters; including a quantized representation of the selected spatial coding parameter into a parameter section of an audio bitstream; and setting a parameter type flag in the parameter section of the audio bitstream indicating the type of the selected spatial coding parameter being included into the audio bitstream.</p> |
